If you"ve been waiting for an easy to use tool for jailbreaking your iPhone or iPod touch, look no further. The iPhone Dev Team never ceases to amaze the jailbreak community, and their latest version of redsn0w is no different. Bursting with support for iPhones and iPod touch, for all generations and OS versions (note: some newer models require a tethered reboot; see the support page for details), redsn0w can be used from Mac OS or Windows based machines (Linux coming soon).
This version has the ability of jailbreaking your device without requiring you to use iTunes. Previously, iTunes was needed to re-load the custom firmware that jailbreaking programs, such as PwnageTool, would package together. Redsn0w also prevents the iPhone"s baseband from being upgraded, allowing users to freely update without accidentally bricking their phones.
Redsn0w will modify the iPhone OS file system and install Cydia. This will give you access to the world of jailbroken apps. If you already have a jailbroken device, redsn0w can still be used to change your boot logos, revert back to the standard logos, or switch verbose booting on or off (that"s where it shows you all the boot code as the device loads the OS). In the next release (0.9.3), redsn0w will enable iPhone users to tether their data connection. Redsn0w can be downloaded from these links:
